I'm not trying to troll or anything of the sort, but this may cause some controversy. It is generally perceived in the area of firearms that MIM parts are not as good as forgings or parts made from billet. I knew this even before I knew what MIM stood for or even was. Well, I'm in school now for engineering with a focus on manufacturing engineering. Right now we are discussing various metal-processing techniques, and I even get to cast my own steel part sometime next week which should be really fun. Anyways, my textbook says that MIM, when done properly, produces small parts of superior strength to billet. It says also that the injection process produces better grain alignment. I haven't asked my instructor about it, but I will.
